For each 10L of water 1 pump added once a week should be used to achieve the typical weekly micronutrient dosing. If plants show signs of deficiency such as yellowing of young (new) leaves then double the weekly dosage.

Avoid dosing this product at the same time as macronutrient products that contain Phosphate, otherwise there is a greater chance of precipitates forming which can cloud the water and will reduce it's nutritional value.
